"Design for the Public Good Gallery"
The Communication Arts website offers an article on design for the public good, including a great gallery of public design. The examples range from a poster for a film festival to beautiful brochure for Doctors without Borders. You can click oneach and read about the project and designer.

It is easy to be distracted by the gallery, but be sure to read the article too. It does a nice job of giving a balanced view of the pros and cons to doing pro bono work as a designer.
